In the procedure, doctors implanted two small metal mesh stents in a coronary artery to aid bloodflow.

在手术过程，医生在冠状植入了两个小金属网以促进血液流。

In the biomedical sector, the pseudo-elasticity of SMAs has made them invaluable in the manufacture of self-expanding stents.

在生物医学领域，SMA 的伪弹性使其在自扩张的制造具有无可估量的价值。

Millions of stents are delivered each year, not in the OR, but in the cath lab or catheter laboratory.

每年交付数百万个， 不是在手术室，而是在导管实验室或导管实验室。

And then also heart stents or any medical device like a heart rate monitor or a prosthetic, those are all made by biomedical engineers.

另外，心脏或是心率监视器和假肢等医疗设备，这些是生物医学工程师制造出来的。

As expected, even after eight hours, let alone a month, the uncoated and the polydopamine-coated stents were saturated in cell growth triggered by immune activity.

正如预期的那样，即使在八个小时后，未涂层和多巴胺涂层在免疫活引发的细胞生长已经饱和，更不用说一个月了。

You could put stents in, etc., etc. But to do this on a animal and a species that you've never done it on before, I think that's just ridiculous.

你可以放置等等。 但是要在你以前从未做过的物和物种上做这件事，我认为这太荒谬了。

They left the rest in place, allowed the animals to recover from the surgery, and then let them go about their lives for a month before killing them and collecting their stents for analysis.

其余的继续保留，让物从手术恢复过来，然后让它们继续生活一个月，然后杀死它们，收集它们的进行分析。

To that end they picked a group of rabbits and implanted into their abdominal aortas stents which had no coating, stents coated only in polydopamine, and stents which had also had platelet membranes attached to them.

为此，他们挑选了一组兔子，将没有涂层的、只涂有聚多巴胺的和有血小板膜附着的植入它们的腹主。
